Hi, The master is running fine. But the slave is using high cpu ~80% constantly for the past couple of hours. The following log fragement repeats. Any idea why?

Hey, this exception basically only tells you, that an expected shard seems not be on this node. The question is merely, why this is the case. Do you have any other exceptions in the logfile of that node, which might give a hint for further problems? --Alex On Wed, Nov 6, 2013 at 6:47 AM, Krishna Kumar Perumalla \< [krishnakumar85@gmail.com](mailto:krishnakumar85@gmail.com)\> wrote: > Hi, > > The master is running fine.
